DETAILED DESCRIPTION
[0010] Embodiments of the present disclosure will be described with
reference to the accompanying drawings.
[0011] Referring to FIGS. 1 and 2, an electronic device 1 for
calculating efficiency of a simulative power supply system 2 is
illustrated. The electronic device 1 includes a processing unit 11,
a storage unit 12, and a display 13. The electronic device 1 can be
a computer, a mobile phone, and an electronic reader, for example.
In the embodiment, the simulative power supply system 2 includes at
least one power supply 21 connected in series. The electronic
device 1 calculates the efficiency of the simulative power supply
system 2 to be designed.
[0012] The storage unit 12 stores a relationship table. The
relationship table defines relationships between a number of power
supplies and efficiencies associated with each of the power
supplies. Such as, the efficiency of an uninterrupted power supply
(UPS) is 90%, the efficiency of a rectifier is 88%.
[0013] The processing unit 11 includes an interface providing
module 10, an input determining module 20, a calculating module 30,
and a display control module 40.
[0014] The interface providing module 10 is used to display a
parameter selection interface 100 as shown in FIG. 2 on the display
13 in response to user operation. The parameter selection interface
100 includes a power supply parameter selection area 110 for
selecting power supply parameters and a transmission line parameter
selection area 120 for selecting transmission line parameters.
[0015] As shown in FIG. 2, the power supply parameter selection
area 110 includes a power supply selection box 101, an output power
selection box 102, and an output voltage selection box 103. The
transmission line parameter selection area 120 includes a
transmission line selection box 110 and a number of parameter
selection boxes. The transmission line selection box 110 is
provided for selecting different types of transmission lines, and
the parameter selection boxes are provided for selecting
transmission line parameters corresponding to the selected
transmission line. In detail, when the transmission line selected
by the user is different, the parameter selection boxes
corresponding to the selected transmission lines are different. For
example, as shown in FIG. 2, when the type of the transmission line
selected by the user is a coaxial cable, the corresponding
parameter selection boxes include a length selection box 111, a
diameter selection box 112, and a conductivity selection box 113.
If the user selects another type of transmission line, the
corresponding parameter selection boxes would be different.
[0016] The power supply selection box 101 is provided for selecting
different types of power supplies 21. For example, the user can
select a UPS, a rectifier, or a converter via the power supply
selection box 101. The output power selection box 102 is provided
for selecting different output powers of the selected power supply
21, such as 20 kilowatt (KW), and the output voltage selection box
103 is provided for selecting the output voltage of the selected
power supply 21, such as 200 volts. In the embodiment, the
transmission line currently selected by the user is used to connect
to the power supply currently selected by the user. Then the
parameter selection interface 100 is provided for selecting each
power supply of the simulative power supply 2 and each transmission
line connected to each power supply.
[0017] Accordingly, the power supply parameters selected by the
user include the type of the power supply 21, the output power of
the selected power supply 21, and the output voltage of the
selected power supply 21. The transmission line parameters include
the type of the transmission line, and the corresponding parameters
of the selected transmission line, such as the length, the
diameter, and the conductivity.
[0018] In the embodiment, the parameter selection interface 100
also includes a confirmation button 130. The input determining
module 20 determines the user has finished the selection when
detecting the confirmation button 120 has been operated by the
user, and obtains the power supply parameters and the transmission
line parameters selected by the user via the power supply parameter
selection area 110 and the transmission line parameter selection
area 120. In the embodiment, the confirmation button 130 is a
virtual button and is displayed on the parameter selection
interface 100. In another embodiment, the confirmation button 130
can be a mechanical button set on a suitable position of the
electronic device 1.
[0019] The calculating module 30 is used to determine the
efficiency of the selected power supply according to the
relationship table, and calculate a sum efficiency of the selected
power supply and the transmission line according to the selected
power supply parameters, the selected transmission line parameters,
and the efficiency of the selected power supply. In the embodiment,
the sum efficiency of the selected power supply and the
transmission line is the sum of the efficiency of the selected
power supply and the efficiency of the selected transmission line.
s
[0020] In detail, the calculating module 30 calculates a resistance
value R of the transmission line according to the parameters. The
parameters include the length, the diameter, and the conductivity,
for example, as selected by the user via the transmission line
parameter selection area 120. In addition, calculates the loss of
the transmission line according to the output voltage selected by
the user via the output voltage selection box 103 and the
resistance value R of the transmission line. That is, assume the
output voltage is U, the loss of the transmission line is Ps, then
the loss of the transmission line is: Ps=U.sup.2/R. The calculating
module 30 also multiplies the output power selected by the user and
the efficiency corresponding to the power supply 21 to obtain a
factual power of the power supply 21 selected by the user. Finally,
the calculating module 30 subtracts the loss Ps of the transmission
line from the factual power of the selected power supply 21 to
obtain an efficient power, and divides the output power by the
efficient power to obtain the sum efficiency of the selected power
supply and the corresponding transmission line.
[0021] The display control module 40 is used to display the sum
efficiency of the selected power supply and the transmission line
on the display unit 13. The display control module 40 is also used
to display a prompt to prompt the user whether to select a next
power supply 21 or not, and determine whether it is needed to
select a next power supply 21 according to the user's selection.
When the display control module 20 determines that it is needed to
select a next power supply 21 according to the user's selection,
the input determining module 20 and the calculating module 30
execute the corresponding function as described above. Namely, the
user selects new power supply parameters and transmission line
parameters again via the parameter selection interface 100, the
input determining module 20 obtains the power supply parameters and
the transmission line parameters selected by the user when
detecting the confirmation button 130 has been operated by the user
once again. The calculating module 30 calculates a sum efficiency
of the next selected power supply and transmission line according
to the efficiency of the next selected power supply and the loss of
the corresponding transmission line accordingly.
[0022] When the display control module 20 determines that it is not
needed to select a next power supply 21 according to the user's
selection, the calculating module 30 determines that all of the
power supplies 21 of the power supply system 2 has been selected,
and calculates a total efficiency of the simulative power supply
system 2 according to the sum efficiencies of each selected power
supply and transmission line. In detail, the calculating module 30
multiplies the sum efficiencies of each selected power supply and
transmission line to obtain the total efficiency of the simulative
power supply system 2. The display control module 40 is also used
to display the total efficiency of the simulative power supply
system 2 on the display unit 13.
[0023] In the embodiment, the parameter selection interface 100
also includes a product information box 104. The product
information box 104 is used to display relative information of the
selected power supply 21, such as a manufacturer, and a manufacture
date.
[0024] Therefore, when the user would design a power supply system
2 for a device (not shown), the user can select the parameters of
the power supplies 21 and the parameters of the corresponding
transmission lines via the electronic device 1, and then the
electronic device 1 calculates the efficiency of the simulative
power supply system 2 according to the selected parameters as
described above.
[0025] Referring to FIG. 3, a flowchart illustrating a method for
calculating efficiency of a power supply system is shown. The
method is applied in the electronic device 1 as shown in
[0026] FIG. 1. In step S301, the interface providing module 10
displays a parameter selection interface 100 on the display 13 for
selecting the power supply parameters and the transmission line
parameters. Therein, the parameter selection interface 100 includes
a power supply parameter selection area 110 and a transmission line
parameter selection area 120. The power supply parameter selection
area 110 includes a power supply selection box 101, an output power
selection box 102, and an output voltage selection box 103. The
transmission line parameter selection area 120 includes a
transmission line selection box 110 and a number of parameter
selection boxes corresponding to a type of a transmission line
selected by the user via the transmission line selection box 110.
Accordingly, the power supply parameters selected by the user
include the type of the power supply 21, the output power of the
selected power supply 21, and the output voltage of the selected
power supply 21. The transmission line parameters include the type
of the transmission line, and the corresponding parameters of the
transmission line, such as the length, the diameter, and the
conductivity.
[0027] In step S302, the input determining module 20 obtains the
power supply parameters and the transmission line parameter
selected by the user via the parameter selection interface 100 when
determining the user has finished the selection. In the embodiment,
the input determining module 20 determines the user has finished
the selection when detecting a confirmation button 130 has been
operated by the user.
[0028] In step S303, the calculating module determines the
efficiency of the selected power supply of the power supply
parameters according to the relationship table, and calculates a
sum efficiency of the selected power supply and transmission line
according to the power supply parameters and the transmission line
parameter obtained by the input determining module 20 and the
efficiency of the selected power supply.
[0029] In detail, the calculating module 30 calculates a resistance
value R of the transmission line according to the parameter, such
as the length, the diameter, and the conductivity selected by the
user via the transmission line parameter selection area 120, and
calculates the loss of the transmission line according to the
output voltage selected by the user via the output voltage
selection box 103 and the resistance value R of the transmission
line. That is, define the output voltage is U, the loss
transmission line is Ps, then the loss of the transmission line is:
Ps=U.sup.2/R. The calculating module 30 also multiplies the output
power selected by the user and the efficiency corresponding to the
power supply 21 to obtain a factual power of the power supply 21
selected by the user. Finally, the calculating module 30 subtracts
the loss Ps of the transmission line from the factual power of the
selected power supply 21 to obtain an efficient power, and divides
the output power by the efficient power to obtain the sum
efficiency of the selected power supply and transmission line.
[0030] In step S304, the display control module 40 displays a
prompt to prompt the user whether to select a next power supply 21
or not, and determines whether it is needed to select a next power
supply 21 according to the user's selection. If the display control
module 40 determines it is needed to select a next power supply 21,
the process returns to S302, then the input determining module 20
obtains power supply parameters and transmission line parameter
selected by the user again when determining the user has finished
the selection once again.
[0031] If the display control module 40 determines that it is not
needed to select a next power supply 21, in step S305, the
calculating module 30 calculates a total efficiency of the power
supply system 2 according to the sum efficiencies of each selected
power supply and transmission line. In detail, the calculating
module 30 multiplies the sum efficiencies of each selected power
supply and transmission line to obtain the total efficiency of the
power supply system 2.
[0032] In the embodiment, the method can further include steps: the
display control module 40 displays the sum efficiency after the
calculating module 30 has calculated the sum efficiency, and
displays the total efficiency on the display unit 13 after the
calculating module 30 has calculated the total efficiency.
[0033] It is believed that the present embodiments and their
advantages will be understood from the foregoing description, and
it will be apparent that various changes may be made thereto
without departing from the spirit and scope of the disclosure or
sacrificing all of its material advantages, the examples
hereinbefore described merely being exemplary embodiments of the
present disclosure.
